port it and tune to like 40hz with a 4 inch aero... I had an sa8 tuned to 40hz in 1.2 cubes on 1000 watts daily and it was loud!!! the higher tuning helps in the ranger because rangers have a very high fs.... I think that it is like 60hz...
Get the dual 2 ohm sub and wire it down to 1 ohm, that amp and sub are a nice set up. I prefer the SA subs sealed but they sound great in either enclosure as long as they are made to specs.
